DUMB-BELL.

SPECIFICATION forming part of Letters Patent No. 734,062, dated July 21, 1903. Application filed February 14, 1903- Serial No. 143,346. (No model.)

the following to be afull, clear, and exact de-' scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to and its object is to provide a dumb-bell in which the distance of the Weights from the hand of the operator and their position in relation to their support may be varied and adjusted.

An important object in the use of a dumbbell is the development of the muscles of the hand and fingers. Much of the benefit to be derived in this particular by the .use of this appliance is lost by reason of the shape of the handle heretofore commonly employed.

Afurther object of myinvention is to provide a handle for a dumb-bell which shall be of such conformation as will permit a firmer and more vigorous grasp of the hand and in which the position of the fingers in relation to the weight may be varied.

My invention is also designed to furnish a dumb-bell which by proper adjustment may be employed for leg and foot exercises.

I attain the objects here indicated by means of the devices and arrangement of parts hereinafter described, and shown and illustrated in the accompanying drawings, in which- Figure 1 is'a side elevation of my dumbbell, and Fig. 2 a central transverse sectional plan view.

Like numerals of reference indicate like parts in both figures.

In the drawings, 1 1. are the weights, usually spherical in form, but which may be of any desired shape, connected by the usual handle 2. Projecting radially from the ends of the handle 2 are arms 3 3, which are paralleland in the same plane. Between the outer extremities of the arms 3 is disposed a handle 4:, Wlll(3l1 in transverse section is somewhat elongated, as shown in Fig. 2, of such dimension as to extend the reach or grasp of the fingers and thumb. Lengthwise through the handle near one of its edges is a hole, which coincides with two corresponding holes in the ends of the arms 3. Through these three holes passes a bolt 5, having at one end a head, the other projecting screw-threaded extremity being provided with a thumb-nut 6. The bolt 5 serves as a pivot or hinge upon which the handle 4 may be swung inwardly, as shown in solid lines in Figs. 1 and 2, or outwardly, as illustrated by the dotted lines, thus varying the distance between the handle and the weight, and consequently varying the leverage and power requisite in manipulating the device and permitting the use of smallerlighter dumb-bells than those of the common form. The handle 4 may be turned on its pivot to any desired position and may be rigidly secured at any point to which it may be turned by setting up the thumb-nut 6, causing the ends of the arms 3 to clamp between them the ends of the handle 4. When thehandle 4: is turned outwardly, as indicated by the dotted lines, there is sufficient space between the handle 2 and the handle 4 to receive the end of the foot, and the dumbbell may now be used as a means for exercising the foot and leg.

An additional advantage of the construction'herein set forth is that my dumb-bells when the handles are extended may be used for nearly all of the movements in which Indian clubs are employed.

If desired, the dumb-bell may be held in the hand byrmeans of the usual handle 2 and used in the ordinary way.

Havingdescribed my invention, what I 3.
